METAL-LINED HOSE.

i To all whom it may concern Be it known that I, HOWARD W. GooDALL,

a citizen of the United States, residin at Aldan, in the county of Delaware and tate of Pennsylvania, have invented a new and useful Metal-Lined Hose, of which the following is a specification.

The principal objects of the present 1nvention are, first, to provide a metal lined hose which can be made in long lengths each having the metal lining co-extensive with the outer part and which may be initially cut and fitted with couplings, or repaired, if worn near the couplings, by cut,- ting out the worn; part and refitting the coupling, and second, to provide a hose adapt- M ed to withstand suction, and also especially applicable for use in connection with oil, gasolene and other substances that attack rubber. r p

The invention will be first described and afterward pointed out in the claims and in giving this description reference will be made to the accompanying drawings forming part hereof and in wh1ch Figure 1, is a. side view, partly in section, with parts broken away of hose embodying features of the invention, and i .Fig. 2, is asimilar view illustrating some of the advantages of the invention.

In the drawings the tube 3,is of any suitable material used for hose, for example,

rubber andduck, or of layers of duck and rubber, or both. The metallic lining 4, consists of substantially half round wires, 1n

- pairs, disposed one 5,'with its flat face, and the other 6, with itsround face,- toward the surface of the bore of the tube 3, said round and flat faces being flush and'each in contact with the surface of the bore of the tube 3, and each arranged in the form of a spiral having a pitch substantially equal to the width of the fiat face of the other. This metallic. lining- 4, is co-extensive with the tube '3, so that thehose can be made in long lengths and cut'to suit any requirements. This' is practically possible because an externally bevel (1 coupling sleeve a, Fig. 2,

can be inserted between the tube 3, and the lining 4, due to the peculiar structure of the 3, from reaching it, and it also supports the Specification of Letters Patent; Patented J l 26, 1 2 Application filed August 31, 1920. Serial No. 407,080.

results is promoted by reason of the fact that the liningand tube are co-extensive. In 1ts adaptability to the application of the de- SCIlbGd co upl1ng member, the construction of the l1n1ng is important, because it provldes the same internal diameter through the hose and coupling. Hose usually fails or wears near the coupling member andsince the described hose can'receive the coupling member a, between its outer or rubber part 3, and 1ts metal lining 4, by reason of the pecullar construction of the latter, it follows that the worn part can be cut out and the coupllng re-applied. 7, is/ a layer of canvas or the like arranged between the metallic limng 4, and the tube 3, and when present it facilitates the accomplishment of the described results. 7 is a braiding of relat vely fine wire which when present as 1n Fig. 1 but not in Fig. 2, holds the metalllc lin ng 4, in shape and also affords a rough grlpping surface between it and the canvas The described hose is very flexible and durable and. its durability is increased by reason of the fact that the metal llnlng extends to the coupling and into one of its elements.

I claim:

1. Metal lined hose in which the outer rubber and the metal lining parts. are co-extensive and which is adapted to receive "a tagering coupling sleeve between its outer ru her and metal lining parts of which the latter comprises a pair of substantially half round wires disposed one with its flat face and the other with its round face toward the inner surface of the outer rubber part, said round and flat faces being flush and in contact with said inner surface and each arranged in the form of a spiral having a pitch substantially ,equal to the width of the fiat face of the other, substantially as described.

2. Metal lined hose in which the outer rubber and the metal lining parts are co-extensive and are provided between them with a textile layer and which is adapted to receive a coupling sleeve between the textile layer and the metal lining which comprises a pair of substantiall half round wires disposed one with its at face and the other with its round face toward the inner surface of the textile layer, said round and flat faces being flush. and in contact with said inner rubber walljeven if weakened by the. acti'on-,., surface and each arranged in the form of a of such fluids or if subjected to the action""spiral having a" pitch substantially equal to flat face and the the width of-the flat face of the other, substantially as described.

3. Metal tube of rubber material, and a, lining coterminal with the tube and consisting of spirally arranged substantially; half round wires disposed in contact and one with its ii: the same. cylindrical plane and toward t e inner surface of the tube and providing a union between the parts which can be readily separated for the reception of a conling sleeve, substantially as described.

4. Metal lined hose in which the outer rubber and the metal lining parts are coextensive and are provided between them and with a layer of wire braiding and textile and which is adaptedto receive a coupling,

sleeve between the layer of wire braiding and textile, and the metal lining which comprises a pair of substantially half round wires disposed one with its flat face and the other with its round face toward the inner lined hose comprising anouter other with its round. face a pitch substantially equal surface of the layer of wire braiding textile, said round and fiat faces being flush and in contact with said inner surface and each arranged in the form of a spiral having a pitch substantially equal to the width of the flat face of the other, described.

5; Metal lined hose in which the outer rubber and the metal lining parts areco-extensive and are provided between them with a layer and which is adapted to receive a coupling sleeve between the layer and the metal lining which comprises a pair of si1bstantially half round with its round face toward the inner surface of the layer, said round and flat faces being flush and in contact with said innersurface and each arrangedin the form of a spiral havin to the width 0 the other, substantially as HOWARD W.
